Removing the Old Water Heater
1. Turn "OFF" electrical supply to the water heater.
FIGURE 1.
The water passing out of the drain valve may be extremely hot.
To avoid being scalded, make sure all connections are tight
and that the water flow is directed away from any person.
4.
Check again to make sure the electrical supply is turned
"OFF" to the water heater. Then unplug the water heater
(cord set) or disconnect the electrical supply connection
from the water heater junction box.
FIGURE 4.
5a.
If you have copper piping to the water heater, the two
copper water pipes can be cut with a hacksaw
approximately four inches away from where they connect
to the water heater. This will avoid cutting off the pipes too
short. Additional cuts can be made later if necessary.
Disconnect the temperature-pressure relief valve drain line.
When the water heater is drained, disconnect the hose
from the drain valve. Close the drain valve. The water heater
is now completely disconnected and ready to be removed.
2. Turn "OFF" the water supply to the water heater at the water
shut-off valve or water meter.
FIGURE 2.
3. Attach a hose to the water heater drain valve and put the
other end in a floor drain or outdoors. Open the water drain
valve. Open a nearby hot water faucet which will relieve
pressure in the water heater and speed draining.

5b. If you have galvanized pipe to the water heater, loosen the
two galvanized pipes with a pipe wrench at the union in
each line. Also disconnect the piping remaining to the water
heater. These pieces should be saved since they may be
needed when reconnecting the new water heater.
Disconnect the temperature-pressure relief valve drain line.
When the water heater is drained, disconnect the hose
from the drain valve. Close the drain valve. The water heater
is now completely disconnected and ready to be removed.
, Keep hands clear of drain
valve discharge.

much heavier than normal.
® Ifspilled, could cause staining.
Mineral buildup or sediment may have accumulated in the old
water heater. This causes the water heater to be much heavier
than normal and this residue, if spilled out, could cause staining.
Facts to Consider About the Location
You should carefully choose an indoor location for the new
water heater, because the placement is a very important
consideration for the safety of the occupants in the building
and for the most economical use of the appliance. This water
heater is not intended for outdoor installation.
Whether replacing an old water heater or putting the water
heater in a new location, the following critical points must be
observed.
The location selected should be indoors as close to and as
centralized with the water piping system as possible. This
water heater, as well as all water heaters, will eventually
leak. Do not install without adequate drainage provisions
so water flow will not cause damage.
• Water supply shut-off devices that activate based on the water
pressure differential between the cold water and hot water
pipes connected to the water heater.
Installations in Residential Garages
. Water heater must be located in a
protective area.
INSTALLATION IN RESIDENTIAL GARAGES: The water heater
must be located and/or protected so it is not subject to physical
damage by a moving vehicle.
The location selection must provide adequate clearances
for servicing and proper operation of the water heater.
Insulation Blankets
Insulation blankets are available to the general public for
external use on electric water heaters but are not necessary
with this product. The purpose of an insulation blanket is to
reduce the standby heat loss encountered with storage tank
heaters. Your water heater meets or exceeds the National
Appliance Energy Conversation Act standards with respect to
insulation and standby loss requirements, making an insulation
blanket unnecessary.
Property Damage Hazard
* All water heaters eventually leak
Do not install without adequate drainage.
WATER HEATERS EVENTUALLY LEAK: Installation of the water
heater must be accomplished in such a manner that if the tank
or any connections should leak, the flow of water will not cause
damage to the structure. When such locations cannot be
avoided, a suitable drain pan should be installed under the
water heater. Drain pans are available at your local Sears stores.
Such drain pans must be piped to an adequate drain.
Water heater life depends upon water quality, water pressure
and the environment in which the water heater is installed.
Water heaters are sometimes installed in locations where
leakage may result in property damage, even with the use of a
drain pan piped to a drain. However, unanticipated damage
can be reduced or prevented by a leak detector or water shut-
off device used in conjunction with a piped drain pan. These
devices are available from some plumbing supply wholesalers
and retailers, and detect and react to leakage in various ways:
• Sensors mounted in the drain pan that trigger an alarm or
turn off the incoming water to the water heater when leakage
is detected.
Should you choose to apply an insulation blanket to this heater,
you should follow these instructions below. Failure to follow
these instructions can result in fire, serious personal injury, or
death.
Do not cover the temperature and pressure relief (T & P)
valve with an insulation blanket.
Do not cover the instruction manual. Keep it on the side of
the water heater or nearby for future reference.
Do obtain new warning and instruction labels for placement
on the blanket directly over the existing labels.
Facts to Consider About the
Convertible Lower Element
The Upper Element (if a double element model) is a
conventional 3800 watt element which only operates at its rated
wattage on 240 volts. (See rating plate on the water heater).
The Lower Element of the water heater can be converted from
operation at 3800 watts to 5500 watts on a 240 volt system.
Read and follow water heater warnings and instructions. If
after reading these instructions in this manual, you do not
understand any portion, call Sears Service Center.
Fire Hazard / Electric Shock Hazard
- Do not use this water heater with
any voltage other than shown on the
model rating plate.
- Failure to use the correct voltage
shown on the model rating plate
could result in death, serious bodily
injury, or property damage.
Before making the conversion to 5500 watts, check the (1)
power supply . . . must be 240 volts, (2) wiring . . . 10 gauge
AWG @ Type TW, 60°C or equivalent, and (3) Circuit breakers
or fusing . . .capable of 30 amp loading. Also, the installation
must conform with this manual, local codes and electric utility
rules. Failure to comply can result in DEATH, SERIOUS BODILY
INJURY, OR PROPERTY DAMAGE.
HOTTER WATER CAN SCALD: Water heaters are intended to
produce hot water. Water heated to a temperature which will
satisfy clothes washing, dish washing, and other sanitizing
needs can scald and permanently injure you upon contact.
Some people are more likely to be permanently injured by hot
water than others. These include the elderly, children, the infirm,
or physically/mentally handicapped. If anyone using hot water
in your home fits into one of these groups or if there is a local
code or state law requiring a certain temperature water at the
hot water tap, then you must take special precautions. In
addition to using the lowest possible temperature setting that
satisfies your hot water needs, a means such as a mixing
valve, should be used at the hot water taps used by these
people or at the water heater. Mixing valves are available at
plumbing supply or hardware stores. Follow manufacturers
instructions for installation of the valves. Before changing the
factory setting on the thermostat, read the "Temperature
Regulation" section in this manual.
See Figure 7 (below) for mixing valve usage.

If a water heater is installed in a closed water supply system;
such as one having a back-flow preventer, check valve, water
meter with a check valve, etc.., in the cold water supply; means
must be provided to control thermal expansion. Contact the
local utility or Sears Service Center on how to control this
situation.
NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adapter to the water inlet connection.
Do not solder the water supply lines directly to the cold water
inlet. It will harm the dip tube and damage the tank.
Property Damage Hazard
• Avoid water heater damage.
• Install thermal expansion tank if necessary.
• Do not apply heat to cold water inlet.
• Contact qualified installer or service agency.
NOTE:Toprotectagainstuntimelycorrosionofhot and cold
water fittings, it is strongly recommended that di=electric
unions or couplings be installed on this water heater when
connected to copper pipe.
1. Look at the top cover of the water heater. The hot water outlet
is marked hot. Put two or three turns of teflon tape around
the threaded end of the threaded-to-sweat coupling and
around both ends of the 3/4" threaded nipple. Using flexible
connectors, connect the hot water pipe to the hot water outlet
of the water heater.
2. Look at the top cover of the water heater. The cold water inlet
is marked cold. Put two or three turns of teflon tape around
the threaded end of the threaded-to-sweat coupling and
around both ends of the 3/4" threaded nipple. Using flexible
connectors, connect the cold water pipe to the cold water
inlet of the water heater.
Fit T & P valve insulation over valve. Make sure that the insulation
does not interfere with the lever of the T & P valve.
Secure all insulation using tape.
NOTE: Your water heater is insulated to minimize heat loss
from the tank. Further reduction in heat loss can be
accomplished by insulating the hot water lines from the
water heater.

cover of the heater.
If replaced, the valve must meet the requirements of local
codes, but not less than a combination temperature and
pressure relief valve certified as indicated in the above
paragraph.
The valve must be marked with a maximum set pressure not to
exceed the marked hydrostatic working pressure of the water
heater (150 psi = 1,035 kPa) and a discharge capacity not less
than the water heater input rate as shown on the model rating
plate. (For electric heaters, watts x 3.412 equals Btu/hr input
rate)
For safe operation of the water heater, the relief valve must not
be removed from its designated opening nor plugged.
The temperature-pressure relief valve must be installed directly
into the fitting of the water heater designed for the relief valve.
